BTA CHEM Unit 8 Climate change content

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and water vapor.

Front

How does carbon dioxide contribute to climate change?

Back

Carbon dioxide traps heat in the atmosphere, leading to an increase in global temperatures, which contributes to climate change.

Front

What role does water vapor play in the atmosphere?

Back

Water vapor is a significant greenhouse gas that absorbs and re-emits infrared radiation, enhancing the greenhouse effect.

Front

What is the primary source of increased carbon dioxide in the atmosphere?

Back

The primary source of increased carbon dioxide is the burning of fossil fuels, such as coal, oil, and natural gas.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen, reducing CO2 levels in the atmosphere.

Front

What is the impact of deforestation on carbon dioxide levels?

Back

Deforestation reduces the number of trees available to absorb CO2, leading to higher levels of carbon dioxide in the atmosphere.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily driven by human activities.

Front

How do seasonal changes affect carbon dioxide levels?

Back

Seasonal changes affect carbon dioxide levels due to variations in photosynthesis rates; during spring and summer, plants absorb more CO2, lowering atmospheric levels.

Front

What is the relationship between fossil fuel consumption and climate change?

Back

Increased fossil fuel consumption releases more greenhouse gases, particularly CO2, into the atmosphere, exacerbating climate change.
